Emma Watson, Victoria Beckham wow with UN speeches

5 Strong women we'd like to see address the United Nations next

"I decided that I was a feminist," the actress said, explaining that her campaign exists to spur men to join women in advocating for gender equality. "This seemed uncomplicated to me. But my recent research has shown me that feminism has become an unpopular word. Women are choosing not to identify as feminists. Apparently, [women's expression is] seen as too strong, too aggressive, anti-men, unattractive."

Now, Victoria Beckham has joined Watson in speaking to the UN in favor of a cause dear to her heart: ending HIV transmission to newborns.

Let's keep more admirable women and their causes coming to the United Nations stage. Here are the powerful women we would like to see address the world's leaders next.

Roberts has been a longtime supporter of the Gay, Lesbian and Straight Education Network, an organization that promotes LGBT awareness and safe schools through national campaigns like the GLSEN Day of Silence and No Name-Calling Week, both of which have been used in tens of thousands of classrooms nationwide. She donated a "Lunch with Julia Roberts" to a fundraiser for GSLEN, which netted more than $40,000 for the organization.

2. Kerry Washington

Scandal star, Kerry Washington, is relatively new to the activist scene, but she's taking it by storm — in light of a number of high-profile allegations of domestic abuse allegations against NFL players, Ray Rice and Ray McDonald, Washington is fighting back against domestic violence as the spokeswoman for the Allstate Foundation Purple Purse Program, which raises awareness of a lesser-known form of domestic violence — financial abuse.

3. Beyoncé

You just knew Queen Bey would end up on this list. Beyoncé absolutely kills at charity — from secretly donating more than $7 million to Houston's homeless, to donating school supplies to at-risk kids. Bey has an entire website dedicated to #BeyGood, her charity that has a simple, yet powerful, message: Help those less fortunate than you.

"The ReThink campaign is really close to my heart because I know firsthand what it's like to not have a stable place to live — and to have stereotypes put on you about what people think of you just because you're at a disadvantage," she says.
